To all w tom 'it may concern Be it known that I, VPani, KUrinn, a citi-k zen of the Unitedl States, residing atQSOO Grange avenue, Birmingham, Stateo-Ala hania, have invented certain newand useful Improvements in Ear Supporters andv Di-` videis for Concrete Slabs, of which the iollowing is a speciiication.

lThis invention relates to in'iproveinents n bar supporters and dividers ttor concrete la s.

' rlie object of the invention is to provide siinple andinexpensive ineans ior convenientljf supportingand securing reinforcing bars. at Vany required distance in concrete slab construction, so that the reinforcing bars cannot shift while the concrete is losing'V put in. p

ii 'further objectoi the invention is to preside a support adapted to engage reinforcing bars at definite distances in the length .oi' a slab, `and to holdsaid bars in fixed relative position irointhe ceiling when' putting in the concrete.

The invention also coiiiprehends improve- Y niente in the details oi'lconstructio'n and. ar-

rangement of Darts which will be vhereinafter described and'particulaily pointed out steadiness ofposition when in use.v The l length of theV support are two rows cut-outs on one/side are disposed out of alineinent-V with the cut-outs on the opposite side,'hence the' tongues on one side are disposed in a plane'interniediate the tongues y on theopposite side.

Intermediate the cuteouts on thellongitudinal edges and disposed throughout the of prongs or tongues 6, formed by cutting out the nietal and bending saine upwardlyat an in eline. These prongs extend inY anopposite direction from the tongues 3, hence affording Vem#` a positive anchor when the support is `Vprongs of one row i These rodsai'e ranged kvbars locked in set-position.y

being disposed to overlap the plane of row. lnk addition'to the prongs acting as anchoring means, they also serve as a ineans' binding rods 7, in position.l

onei'ow the bars will be acertain distance Y apart, while if `this distance is to be decreased, aiid a'kgreater nuinber of bars is tov be provided, then the companion row of prongs will be .brought into use. The invention ytherefore not onlyprovides special means tor anchoring the support in concrete,

but in addition it affords specific and safe means for effectively holding the reinforcing when the niass of concrete is placed around l the whole structure is reinforced throughout. The prongs are bent around the bars to embrace saine as vtightly as possible, and when the concrete is put in place it flows, or is packed aroundthe bent portion and forins an eiiective binder. The concrete also passes through the openings forniedfby the tongues, consequentlyV stresses in all directions are taken care of.

Consequently `While` the invention described acts as a i the concrete, its prinieiiiportance is to' form ineans for rigidly holding ing when putting inthe concrete.

lllVhat'I claim iszl. A support for concrete comprising a p fiat strip of metal having two longitudinal edges provided with cut-out portions and depending` tongues adjacent said cut-out portions, said tongues being fornied by the nietal 'from the cut-out portions, the cut-out poi'- tions on one edgeV being out of alineinent with the cut-outk portions on the oppositeV edge, theiiat strip havingtwo longitudinal rows of prongs all extending in the saine di rcction and strip, the prongs of one row being disposed to overlapthe plane of the ends of the adjacent row, and bars extending Vacross the the reinforcing bars in the ceilico fioiiiend to end of the strip and extending upwardly from the surface of the o strip and secured by bending certain of theV i prongs over said bars. Y

2. A support of the character `described comprising a flat nietal plate, projections on opposite longitudinal l edges,

with a plural i ity, of projections,V the projections on one edge being out of alineinent Jeetions on the one end of each with the prothe metal at extended from the metal plate between the fout out edges, the rows of pro ngs extending i V'beyond the fixed end throughont the length of the plate,v thev free endsV of 'thek prongs in one row terminating adjacent row. Y

In testimony whereof I affix my signature.
